there was only a single fertile egg in the batch. The 

 •oldest of the three is now identical in appearance 

 with the bird I received from German\\ now a stuffed 

 specimen. The second is fast becoming similar, the 

 only difference being that there is less lattice work on 

 the wings. The youngest has as yet no lattice work 

 on the v/ings. I do not know the sex of either, but

 themselves about when the cage is approached. 



I sent the oldest bird to the Crystal Palace Show 

 in January, 1904. He was then little more than three 

 months old and did not look so smart as he does now. 

 I was told he looked very ill there. I can only 

 suppose he had been dashing himself about, for he 

 was in the best of health before, and has been so ever 

 since.

I AM tempted to elaborate at some length the life 

 history of two broods of j'oung birds that were 

 raised in May and June, 1903, that definite data 

 may be before the reader and student, as to 

 exactly what has occurred for the past year with the 

 individuals under observation. 



On the 7th of June, 1903, I found a nest of Rose-
